Temperature measurement by resistance thermometers relies on a property common to all conductors and semiconductors, which is the variation in their electrical resistance in relation to temperature change.
The PT1000 sensor has an ohmic value of 1000 at a temperature of 0°C.
Differing from the more common PT100 sensor, the stronger signal of the PT1000 provides greater accuracy and eliminates the presence of the third wire necessary to compensate the ohmic value of the cable. The reading range and construction of this sensor make it suitable for air conditioning or industrial process systems with decimal precision.
